基于MPLS技术的VPN研究

Research of VPN based on MPLS technology

多协议标签交换(MPLS)是目前IP网络的核心技术,MPLS VPN也将成为构建VPN网络的主流技术。介绍了MPLSVPN的产生背景,对MPLS VPN的体系结构作了详细的分析,包括MPLS中的几个比较重要的概念和MPLS VPN的工作过程,阐述了MPLSVPN的优势和发展前景。

As the core technology of the current IP network, the multi-protocol label switch （ MPLS ） is also expected to come to be the mainstream technology of constructing the virtual private network （VPN） network. This paper introduces the generating background of MPLS VPN, and makes detail analysis on the architecture of MPLS VPN, which includes several more important concepts in MPLS and the working process of MPLS VPN, and expounds the advantage and developing prospect of MPLS VPN.
